Subject Re: Cannot conect while using ActiveMQ with Qpid JMS client
Date Tue, 19 Jul 2016 09:12:47 GMT
Can you check which versions of proton-j are on the classpath? A
likely related report came up a couple of weeks ago, where someone was
trying to use the JMS client and another client together in the same
VM, but the latter embedded a fairly old version of proton-j which
lacks some newer methods the JMS client is using. That caused
behaviour similar to what you describe if the older proton-j version
came first on the classpath. I haven't yet had a look into where it is
misbehaving inside the client to try and improve the behaviour when it
does. The 0.10.0 release actually uses that version of the broker in
some of its tests, for what its worth.
